I have a Neom diffuser and it's lovely, I use Neom's oils or White Company. I use one for about a month then change.
At the start of the day it's lovely but by the afternoon it really stinks coming out.
I have scrubbed the hell out of it with fairy inside and out every time I switch oils, I've been cleaning it thoroughly daily now to try and get the smell away. It smells fine, and like I say starts off fine, but then it smells... funky. I put fresh water and oil in every morning.
Why is this happening, and what can I do please?
